very nice Master Hal, I would love to see the pics of the 20 different ones. I am designing a fold up table made of plywood. Since edges will be banded, I am looking for a design that makes that fairly easy. These are the parameters I am working with
Here is the parameters I set for my table1: Seat 62: no obvious modern hardware when set up (like catches hanging loose)3: under $100 preferable $120 top end4: one person to handle move and setup5: period at first glance. The last one had period shape but looked.. off6: no loose parts to store when setup, ( darn lost the..)7: small enough to transport, longest dimension 36"8: NO TOOLS to setup9: easy to make with minimal tools, ie circular saw and a couple chisels (tablesaw still easier)10: simple plans to share with my friends

Some where around I have sketches and photos of about 20 different styles of trestles. The photo is of the style I settled on for its ability to brake down. The original that I had seen in York came apart into a front A frame and the top cross and back leg mortised and tendon to form an L shape. The two pieces half slot together. I have since modified the back leg so it to is removable for easy set up and take down, with a through tendon. I'll try and find my sketches and photos to post later.
